Inhibition of human MAP2K1 in HL-60 cells lysate assessed as reduction of labeling of acyl-phosphate ATP probe at 100 nM

We previously disclosed tricylic, 6-carboxylic acid-bearing 4-quinolones as GSK-3beta inhibitors. Herein we discuss the optimization of this series to yield a series of more potent 6-nitrile analogs with insignificant anti-microbial activity. Finally, kinase profiling indicated that members of this class were highly specific GSK-3 inhibitors. ..more
